Description

The Arista 7020R4 Switch Router delivers 48x25GbE SFP28 and 4x100GbE QSFP ports in a compact 1RU form factor, purpose-built for data centre leaf, service provider access, and high-performance edge deployments. With up to 2 Tbps switching throughput and 900 Mpps forwarding rate, its deep-buffer VOQ architecture and FlexRoute™ engine — scaling to over 2.5 million routes — make it ideal for internet peering, EVPN-VXLAN fabrics, and service provider environments demanding carrier-grade scale without compromise.

Built on Arista's 7th Generation R Series architecture, the DCS-7020R4-48Y-4QC-R supports wire-speed TunnelSec™ encryption (MACsec, IPsec, VXLANsec), full MPLS and Segment Routing, IEEE 1588/PTP precision timing, and comprehensive streaming telemetry — all managed via Arista EOS® with Zero Touch Provisioning. Rear-to-front airflow and dual hot-swappable AC power supplies ensure operational resilience in demanding data centre environments.

FAQs

Q: What is the Arista DCS-7020R4-48Y-4QC-R designed for?
A: The DCS-7020R4-48Y-4QC-R is purpose-built for data centre leaf switching, service provider access, internet peering, and high-performance edge deployments. Its deep-buffer VOQ architecture and FlexRouteâ„¢ engine make it well-suited for environments requiring large route tables, EVPN-VXLAN fabrics, and carrier-grade traffic engineering.

Q: Does the 7020R4 support encryption?
A: Yes. The 7020R4 supports wire-speed TunnelSec™ encryption at both Layer 2 and Layer 3, including MACsec, IPsec, and VXLANsec — all without impacting line-rate forwarding performance.

Q: What routing and tunnelling protocols does the 7020R4 support?
A: The 7020R4 supports a comprehensive suite including MPLS, Segment Routing (SR), EVPN-VXLAN, EVPN-VPWS, EVPN-DCI, IPv4 VPNs (RFC 4364), 6PE/6VPE, LDP, RSVP, GRE, and MPLS over GRE — making it suitable for both data centre and service provider network designs.

Q: What does rear-to-front airflow mean for this switch?
A: Rear-to-front airflow means air enters from the fan/power supply side (rear) and exhausts out the port side (front). This is the 'R' suffix designation and is suited to data centre hot-aisle/cold-aisle containment setups where port-side exhaust is required.

Q: Can I purchase the Arista DCS-7020R4-48Y-4QC-R in Australia?
A: Yes. The DCS-7020R4-48Y-4QC-R is available through IP Trading at iptrading.com.au, with delivery across Australia. Contact the team for pricing, availability, and volume enquiries.

Q: What management and automation capabilities does the 7020R4 offer?
A: The 7020R4 runs Arista EOS®, which provides rich automation, Zero Touch Provisioning (ZTP), comprehensive streaming telemetry, Accelerated sFlow, and Inband Network Telemetry via a flexible programmable pipeline — simplifying large-scale deployments and day-2 operations.
